Ok GP, you have won the auction...
But do not forget, it was an "experimental" project so I do not know what they can cause during a longer period of usage (I mean the higher vibration). It is your responsibility to use them. I think the chassis of the Murena is tough enough, but who knows...
I think you should try to mount it only at one side, start the engine to see and feel the difference and then decide it if it is worth the extra job at the other side.
And if you think these bushes are useable for racing, I will be very happy.
If you are still interested, send me a PM with your postal address and I will send you the bushes. I do not know when, because I will be busy next week...
